Hello,
I have problems with OnInterrupt event. When I try to use this event, System.ArgumentException occurs in Microsoft.SPOT.Hardware.dll (4.3.1.0). Target Framework is 4.3, included GHI libraries are ver. 4.3.6.0. I have used pins P1.15 and P1.16. What is wrong? And general question: Which pins can be set as digital input/output? I can’t find this information anywhere.

@ Jason - What you say may be true but if you use 1.0 ~ 1.31 or 3.0 ~ 3.31 on this system, they are not interrupt capable by processor manufacturer’s hardware design, regardless on how he accesses them.
